Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed design transit device is used, then the structure is simple and easy to manufacture, but it cannot be adapted to different types of cables and pipes
Solution Approach 1:
The transit device is divided into multiple extension frame modules that can be connected in series. Each module can independently accommodate different types of cables and pipes, and the modular structure allows flexibility in configuration to suit various application requirements while maintaining manufacturing simplicity.
Solution Approach 2:
The extension frame modules are designed with universal connection elements that can be used across different module types and configurations. This universal design enables the same basic module structure to serve multiple functions and adapt to different cable/pipe types without requiring entirely different device designs.
2Productivity
If a non-modular transit device is used, then the installation process is straightforward, but it is inefficient and not cost-effective for various applications
Solution Approach 1:
The transit device is segmented into standardized extension frame modules that can be quickly assembled and disconnected. This segmentation enables rapid installation by allowing installers to configure the appropriate number of modules for each application without custom fabrication, significantly improving installation efficiency while maintaining versatility.
Solution Approach 2:
The modular design allows easy adjustment of device parameters such as length, number of cable openings, and configuration by simply adding or removing modules. This parameter adjustability enables the same basic module design to be adapted to different applications without requiring complete redesign, improving both installation efficiency and versatility.
3Reliability
If intumescent material is placed without optimization, then fire protection is provided, but the reaction time is delayed and fire safety is compromised
Solution Approach 1:
The intumescent material is pre-positioned in strategic locations within the extension frame modules, particularly at the fire-exposed surfaces and around cable penetrations. This preliminary positioning ensures that when fire occurs, the material is already in optimal position to react immediately, reducing response time and improving fire protection reliability.
Solution Approach 2:
The intumescent material is applied selectively at critical locations where fire protection is most needed, such as at the fire side of the partition and around individual cable entries. This localized application ensures faster reaction at critical points while optimizing the overall fire protection system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular design enables efficient and cost-effective installation, enhanced fire protection through quick-reacting intumescent material, and improved ventilation and cooling, making the device suitable for a wide range of applications.
Implementation Method 1
Intumescent material is a material that swells when exposed to excessive heat, such as in case of fire. The intumescent material may function as insulation material for the cables when a fire occur.
Implementation Method 2
The holes of the extension frame on the non-fire side will ventilate the frame and thereby cool the cables.
